StarModuleSLC910 Integration Guide.doc Preliminary Confidential page 2 of 4 DATALOGIC PROPRIETARY INFORMATIONS Introduction The StarModuleSLC910 is an FSK RF half-duplex transceiver working at 910MHz, made to be installed on fixed or mobile devices. Digital interface Digital Interface with host system: Data communication with host is implemented using a UART @38400, N, 8, 1 Control is implemented using IDLE/RX line and receiving Carrier Detect indication. Pinout TOP VIEW IDLE/RX Function HIGH Sleep LOW Rx mode Receive data on TX_DATA, CD# asserted means RF channel is busy RF interface StarModuleSLC910 has 50 Ohm impedance on RF out in TX and RX mode, therefore impedance matching is required for antenna system of host. Care must be taken for the proximity of conductive materials or the user’s hand that will cause a mismatch of the antenna, decreasing the transceiver RF characteristics. Moreover, care must be taken to ensure that the host system doesn’t have spurious emissions in the range 910MHz+/-100kHz, that could cripple receiver sensitivity: it is advised to put a ground plane under the RF module and to filter the power supply. Noisy parts, like system buses, must be shielded in order not to irradiate spurious fields.
